you need to use wireless bridges or an access point that could function as a repeater
Network 1 has the router and the internet connection.
Network 2 needs to be able to use the internet aswell.

First of all, you only need one router, not two.
If your wireless router allows you to set up the wireless portion as a wireless bridge, do that. And take another simple wireless access point on the other side to make the bridge.
If not, you'll need to buy two wireless access points and connect one on each side.

Here's a basic layout using a separate wireless bridge:
[wired router]---[wireless bridge]   ))))((((  [wireless bridge]----[switch]

And the same layout if your wireless router supports bridging:
[wireless router]   ))))((((  [wireless bridge]----[switch]

Of course you'd connect your wired devices in each room using switches.
For all practical purposes, consider the wireless link as a really long cable.
Worst case scenario, you might have to assign static IPs to the computers on the far side. Usually DHCP broadcasts are carried over, but I've seen it not happen that's why I mentioned it.
Otherwise, you should be set
Connect your wireless router wan port to the wired router.
Both will give out DHCP of different network. NAT required on wireless router.

Generally, it's not advisable to double-up routers.
Generally, networking always faces a cost issue.
Hence, if you need 2 different networks to connect to internet, refer to my post above.
If you can make do with everyone in a single network, just set the wireless router as an AP.
Agreed, but I thought there were two rooms with a few computers in each room.

Let's assume that the computers in each room are already connected to eachother using simple Cat5 and a switch. Or the switch built into the router in the case of Room2 that has the internet connection.
All that needs to be done then is to connect Room1 to Room2 so that the computers in Room1 can leech the internet off of Room2.
The wireless bridge will only function as a really long cable. That's all.
What I'm suggesting is that both rooms are kept in the same subnet. All computers will acquire IPs from one DHCP server - the router in Room2.
Now all that remains to be seen is whether the wireless router can do bridging. In which case all you need to buy is one wireless access point that'll sit in Room1.
If the wireless router cannot do that, you'll need two access points to do the bridge.

That's as simple as it gets (save for running a piece of Cat5 from Room1 to Room2).
